Conservation of threatened species often uses habitat models to inform management of habitat and populations. We examined habitat use by Bicknell’s Thrush (Catharus bicknelli (Ridgway, 1882)), a federally “Threatened” species, in two Appalachian
regions, shaped by forestry activities, of southern Quebec. Within its breeding range, the species inhabits mountain tops
and forests subjected to various logging activities. We assessed the role of vegetation and topography at two spatial scales, as well
as spatial relationships with Swainson’s Thrush (Catharus ustulatus (Nuttall, 1840)), identified as a potential competitor by some
authors. In both regions, Bicknell’s Thrushes were most likely to be reported at high elevations, in forest stands with high tree
stem densities that underwent little or no stem reduction from forestry activities. Swainson’s Thrushes were present at all sites
were Bicknell’s Thrushes were reported. These results are consistent with findings from studies in northeastern parts of its
breeding range. We conclude that forest-stand thinning should be kept to a minimum throughout the high-elevation nesting
habitat of Bicknell’s Thrush.
